AMOS WHITTEMORE, OF OAMBRIDGEPORT, MASSACHUSETTS.

IMPROVEMENT IN STREET-RAILWAY TURN-OUTS.

Specification forming part of Letters Patent No. 177,603, dated May 16,1876; application filed November 20, 1875.

To all whom it may concern Be itv known that I-,-AMos WHITTEMORE, ofCambridgeport, in the county of Middlesex and State of Massachusetts,have invented a new and valuable Improvement in Horse-Oar- Rail Switch;and I do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing bad to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure-1 of the drawings is a representation of a plan view of myswitch, and Figs. ,2 and3 transverse sectional views of the railthereof.

This invention has relation to horse-car railroads; and the nature of myinvention consists in a novel arrangement of guard-flanges with relationto sections of the track-rails where there are sidings or turn-outs fromthe main rails, as will be hereinafter explained.

It is a very common occurrence for streetcars to leave the track inswitching from a main track to a side track, and vice versa,

and the object of my invention is to obviate this source of trouble.

In the annexed drawing, A A designate the straight main-track rails, andB B designate the turnout or siding rails branching off from themain-track rails. The sections between the main rails and the turn-outrails have flanges G 0 formed on them, which are on the outside of, andextend above, the rollingsurt'aces of their respective rail-sections.The guard-flange G is about the center of the main turn-out rail, andextends along the entire distance where the wheels are liable to jumpthe rail while the driver is turning his car from the main track to theside or branch track. Should there be a tendency at such point for thewheels to jump the track the outside of the right-hand wheels willstrike the guard-flange O and'prevent displacement of the car. Theguard-flange G on the maintrack. rail is so arranged with relation tothe AMOS WHITTEMORE.
